Asus desktop/ Random Screen Crashes

About three times in three weeks, my screen has crashed/frozen. It's a vertically striped screen of grey and black bars. The PC is still running, and if something has sound I can hear it playing. I can't do anything but physically hit the power button. It's done it once when loading a game screen, and twice when on the internet(just clicking on an open tab.)
The gfx card and PSU aren't stock, I added them back in October/November. HOWEVER, I did recently install Windows 7 Ultimate over Windows 8.1. (It had updated to .1 from 8.0 without me really being able to say no, and nothing was very compatible.)

Any help would be really appreciated and just let me know if you need more info. (please provide simple instructions on how to pull up said info if it's fairly complicated:))

Windows 7 Ultimate SP1
Asus CM1745
AMD A8-5500 APU with Radeon HD Graphics
3.20 GHz
8.00 GB
64 Bit

I don't think that will be possible right now. the cable I use is this

http://www.amazon.com/Cables-26911-DVI-D-Digital-Video/dp/B0000X0VCY/ref=sr_1_1?m=ATVPDKIKX0DER&s=electronics&ie=UTF8&qid=1374711068&sr=1-1&keywords=dvi+cable

I switched over from the stock vga cable back when I changed the PSU and gfx card.

Do you think it could be a driver issue? I'm out of my depth here but I know it started happening after I "downgraded" to windows 7 from 8. While I was on 8 this never happened and that was for about 2 months.

Any other suggestions than using other components?

It just did it again.
When I rebooted and the desktop came up, there was this task that I could highlight but it was just a white box then it went away. It was something like "AMD something transcoding device"

Well it's started happening 1-2 times a day now. I've ran system mechanic, made sure about the drivers etc.
The problem report keeps saying LiveKernelEvent.

I've also had "Windows was able to successfully install device driver software, but the driver software encountered a problem when it tried to run. The problem code is 43."

And video hardware error LiveKernelEvent

I had the hard drive replaced back in November from a PC tech place, when I installed the new PSU this Bios utility screen came up and I couldn't go past it. The tech place spent like 4 days trying to figure out if it was the motherboard or the HD and finally found it to be the latter.

Should I start looking on new egg for MOBOs?

Oh and I've also noticed that when I'm playing graphically demanding games and the volume goes low, I can hear this pulsing "fan-like" rattling sound like something isn't secured properly I don't know...

quick question, my bios is 2.7 last updated 8/27/12

asus.support says there's 5 updates after that improve system stability. Do I just need to do the last one, or all in order?

So far there was one system crash(the grey/black stripe screen) on 2/13/14(Reliability Report just says not properly shut down and I'm not sure if there is a crash report stored somewhere that might prove helpful?) This is much better than once or twice a day and if it was a failing component would it not be happening more frequently? I'm not sure... I will keep this updated. Thanks for taking the time to help again btw!

So far no more crashes except apps(games). I've ran SMART hard drive scan and it looks good. Windows memory diagnostic and no problems. I stress tested my gfx card and no problems. I've ran Prime95 to stress test my CPU but it apparently will finish it's tests in June so I stopped it.... No system crash since 2-13-14 but that was the grey/black striped screen just browsing the internet and after all the updates. Idk hopeful?

I'm thinking maybe upgrading my APU and/or my motherboard soon. My APU is an AMD A8-5500(crap I know..) Since I mostly use my pc for gaming it might improve stability?

... maybe just building a new rig would be better lol I already have a new gfx card, psu and hard drive, might as well replace the rest

I guess I would probably NEED a new motherboard if I am going to upgrade my APU? I don't know anything about slot types/sizes or anything like that. And a better case that allows improved ventilation and space(but that'd be cheap). Should I open a new thread or continue and wait a week or 2 on this one to make sure it's copasetic?

Been over a month! KNOCK ON WOOD. No crashes whatsoever:) I think I am ready to pick your driver and BIOS update as solution!

Although occasionally/rarely I hear what sounds like a grain of dust or plastic or something fall and rattle... Mayhap I'll open it up and make sure it's clean and there aren't any loose components. Probably just dust I hope:)
